Emby Media Server has many client apps including: Kodi, Windows Media Center/XBOX 360 (MCE Extender), Android TV, Roku/Now TV boxes, Amazon Fire TV, some Samsung Smart TVs. This means when you copy local movies to Emby, you can stream your movies with Roku, Koid, WMC, etc. The point here, sometimes, you will find it a painful experience to play MKV files via Emby. And people may encounter problems 'Emby not detecting MKV files' like these:
"I'm having a problem where I can't get my Mkv files to play on the Emby Roku app. I have to either remux the video files and change them to mp4 or watch them using PlayOn. Is there a way to get Emby to play Mkv files?"
"I was able to successfully get my Emby server running on my Ubuntu server. The only issue I have now is that it doesn't play .mkv video files. I'm assuming it's some sort of codec/transcoding issue? I can play .mp4 video files just fine. Is there something I should install to get the .mkv files to play?"
As you see, many folks are facing the MOV playback issues with Emby. Searching from Google and some guys recommend to install K-lite codec pack. I have tried that, however, Media Browser did not use any codecs from external codec packs and whether K-lite was installed or not would make no difference where Media Browser was concerned. Actually, manually installing codecs doesn't actually effect Emby.
